Hello, can somebody explain what do I do wrong that during backtesting, at some point (GBPUSD - 2017.03.06), my EA opens hundreds of sell orders? 

[Marco vd Heijden]

Code it to prevent that.

Always set a safety fuse for ORDERS_MAX to prevent runaway situations.

[Sakkull]

Sorry to say that but I am a noob, could you please elaborate how to do that since there is no ORDERS_MAX function?

[Marco vd Heijden]

In that case please go here: https://www.mql5.com/en/job

You have to create the ORDERS_MAX function yourself, so that it checks the number of open orders and if it is allowed to open more.
